A game about building nightmares so terrifying you’ll see half of them in your dreams afterwards. You have cards representing Night Terrors, and the more of them you combine in the right order, the more monsters will come to life, and the more horrifying they become. Create monsters that will make your opponents gasp in horror. Nourish them with your own fear and make them stronger. Only then will you achieve victory and become the Master of Terror! This edition adds the Legion of Horrors expansion with 12 seal cards. These seals allow you to use creature abilities again and protects from Executioner, Scavenger, and Devourer. Using them is optional; it does not change the base rules but adds some new actions.
